FAQ
Why a love letter to CSV?
CSV is the most universal data format ever created — simple, readable, and everywhere. We celebrate it by giving it a modern JSON twist.
Is my data sent to a server?
No. All conversion happens locally in your browser. Your CSV never leaves your device.
What CSV features are supported?
We handle standard comma-separated values with a header row, quoted fields, and common edge cases. The first row is treated as keys.
Can I convert large CSV files?
Yes, within browser memory limits. For very large files, consider a command-line tool, but for everyday data this works great.
